One problem with Freud's published case histories is that they

A) simply repeat the notes he took during sessions with patients.
B) are based primarily on statements made under hypnosis.
C) sometimes differ from the notes he made after each session with a patient.
D) are based primarily on dream analysis.

Freud's published case histories have been criticized for not being entirely accurate, as they sometimes differ from the notes he made after each session with a patient. It is suggested that Freud may have altered certain details for the purpose of protecting his patients' privacy or to fit his theoretical framework. Therefore, option C is the best choice.
